Is there a night light that only uses 5W for an hour?

First of all, I have to correct it, 5W is the wattage of the night light, do you mean five kilowatt-hours of electricity per hour? I'm sorry, but it shouldn't be possible, and according to a normal five-watt night light, it would take 200 hours to consume one kilowatt-hour of electricity. Also, I guess only Edison can help you with the new invention of the night light.

I bought a night light when I visited the night market before, with a Peking Opera mask, I feel very Anhui style, and there is a recessed nest on the top of the lamp, which can put some essential oils and aromatherapy, which can help sleep, and I am a little afraid of the dark, so such a night light will not be too bright, because it is too bright I can't say, and the wattage is not very high, it is acceptable to point every day and there will be no electricity overrun.

Or you said that you only use five watts an hour, I don't understand, according to my understanding, it is five kilowatts of electricity an hour, then if five kilowatts of electricity is your night light, it must be 5,000 watts, so it is also called a night light, then it is estimated that it will not be found. Because it is the power of high-power appliances, such as refrigerators, washing machines, and induction cookers, what do you want to do with this night light? Filling the house?

It's like a story that a master wanted to teach his skills to three apprentices before he died, so he gave the same amount of money to each of them, and then asked them to buy something and come back to fill the whole house, and the first apprentice bought a lot of firewood, but the money was spent and the house was not filled, and the second person I forgot what he bought, and the third apprentice bought a few candles to fill the whole house with light, so that the third apprentice got the master's craftsmanship.

Do I understand your question according to my understanding, or do I want to read more books, if you can't graduate, you won't read, you will be a teacher for one day and a father for life, if you are not motivated, your father will be sad.

First of all, according to the knowledge of junior high school physics, the power of an electrical appliance is equal to the voltage * current. Normally, the voltage of the family is 220V, and the abnormal includes the peak period of electricity consumption, typhoon period, flood period and other periods of unstable voltage, at which time the voltage is not easy to count.

Assuming that the voltage is stable at 220V, a formula, three conditions, it is known that the power of the bulb is 5W per hour, and the voltage does not change, that is, the single condition does not change, which becomes the primary school mathematics knowledge, find the current. That is to say, your bulb can only allow the current to pass through, which means that the resistance of the bulb is very large, and with the power of one person, it blocks the current of thousands of troops from passing.

Why do you need to discuss resistance when buying a night light, which involves the material of the filament. Different materials have a great difference in the resistance strength of the bulb, and at the same time, there is also a big difference in the service life of the bulb, and this difference is especially obvious in areas where voltage instability is frequent. If you don't believe it, you turn your main gate on and off dozens of times a day, and some lights just burn faster.

There are some particularly beautiful night lights on the market, and they are very cheap, but they are easy to heat up when they are often used, and it feels like they are burning every minute, which is also due to the materials used to make them.

So the question is, which bulbs on the market have relatively large resistances? This is a very forced way to ask, even if you really don't understand, you go to the store to discuss with the boss about the durability of the bulb, the resistance of the wick material, and the boss is forced to give you a discount every minute, it doesn't matter, as long as you can flicker, just tell the boss the keyword 5w.

1000 watts = 1 kilowatt of electricity, your night light is one watt, turn on for 7 hours a day, and it is 7 watts overnight.

You can drive 143 hours of electricity for 1 kilowatt-hour, and 1 kilowatt-hour of electricity is calculated in yuan, which means that you can drive for about 20 nights for 7 dimes!! Hope satisfied.

5w 24 small code friends 30 days to carry 1000 = kilowatt-hours of electricity.

How many degrees are used in 24 hours: 5 1000 = degrees x 24 hours = degrees x local electricity ** = electricity bill.

For example: degree element = yuan 24 hours.

There is no 100 watts per hour of electricity) [only kilowatt hours, that is to say, 1000 watts of electricity per hour].

The analysis is as follows: if you leave it on from 10 p.m. to 6 a.m. at night, for a total of 8 hours, that is, electricity consumption = 1w * 8h = kilowatt-hour of electricity.

1. Watt is a unit of power, symbol: W, kilowatt is a unit of power, symbol: KW, 1 kW = 1000 watts.

Kilowatt electric heating appliances use 1 kWh of electricity for one hour of operation, that is, 1kw·h (kW·h) = 1 kWh of electricity.

1 = 1 kWh for 1000 hours, 1 1000 = kWh for 1 hour.

The method of calculating electricity consumption is as follows: 1 kilowatt of electrical appliances is equal to 1 kilowatt-hour when used for 1 hour, which means 1 kilowatt-hour of electricity.

You can first prepare 4W into kilowatts, imitate Minqin 4W 1000w = kilowatts, and then multiply the power (kilowatts) by time (hours) = kilowatt-hours (degrees). I take a type.

So kilowatt 1 hour = kilowatt hour, which is equal to kilowatt hour.

How much electricity does a 4W light use in an hour? Contains reputational lead.

The calculation method of how much electricity is used: convert 4W into kilowatts.

Kilowatts 1 hour = kilowatt virtual shooting time (degree negotiation is good). (250 hours is 1 degree).

5w 24 hours 30 days 1000 = kWh.

How many degrees are used in 24 hours: 5 1000 = degrees x 24 hours = degrees x local electricity ** = electricity bill.

For example: degree element = yuan 24 hours.

There is no 100 watts per hour of electricity) [only kilowatt hours, that is to say, 1000 watts of electricity per hour].

1 kWh of electricity is 1000 watt-hours.

kWh). The calculation method of the electricity consumed by a 5 watt (W) lamp for 1 hour is as follows: the power (100 watts) should be multiplied by the electricity consumption time (1 hour), that is, the amount of electricity consumed (kWh) multiplied by a day, 24 hours, and then multiplied by 365 days to obtain the kWh.

Power consumption in one year (5*1 1000)*24*365= kWh.

1 kWh 1 kWh, a power of 1 kWh consumes 1 kWh of electricity when working continuously for 1 hour. The calculation formula is: electricity consumption (kW) Power (kW) Use time (hours), 24 hours a day, 30 days per month, 3 * 24 * 30 days 2160W, so degrees.
